My invention relates to a new and useful improvement in a warmair register adapted for use as a warm air register for positioning over the warm air outlet on warm air heating installations. l i

It is an object of the present invention to provide a warm air register so arranged and constructed that the usual control of the warm air issuing Ifrom the outlet may be present and operable, while, at the same time, a means is provided for humidifying the air issuing from the outlet.

Another object of the invention is the provision of a device so constructed and arranged that a large portion of the dust and foreign solid material traveling with the air may be trapped and prevented from issuing into the room.

Another object of the `invention is the provision of a warm air register having a humidify ing` apparatus mounted therein and so arranged and constructed that the air is caused tol travel a i'naximum distance in the moist atmosphere created by `the humidifyingdevice.

Another object of the invention is theprovision of a warm air `register so arranged and constructed that the air issuing therefrom will sue in downwardly directed currents.

Another object of the `invention is the provision of a device ci this classwhich will be simple in structure, economical in manufacture, durable, compact, easily andlquickly installed, and highly efficient in use.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be `best understood by a reference to the accompanying drawing which `forms a part of this specification, and in which:

l isa front, elevational view of the in vention.

Fig. 2 is a sectional View taken on line 'ti-2 of Fig. l, slightly enlarged.

Fig. is a side, elevational view of the in vention.

Fig. a is a fragmentary, sectional view taken conduit. The invention comprises a box-like housing having oppositely disposed side walls Il and l2, a top wall it, a bottom wall I4, and a front wall I5.` Thesides and the top of this house are welded or otherwise suitably secured to a U-shaped frame which projects beyond `the `5 outer surface thereof to forma securing flange it through which screws or other suitable fastening meansare projected for securing the device to the wall 9. l

Pivotally mounted on and positioned between -110 the side walls li and I2 are control shutters Il, each of which is pivoted at its lower end to a rod I8 mounted on these oppositely disposed side `vvalls. Each of these shutters is provided at one of its ends with the outwardly projecting lug It having a slot 2t formed therein through which is extended a pin 2l which serves to connect each of the shutters to an actuating bar 22 which is slideably vertically in contact with the -inner face of the side wall I2. Positioned exterior of the side Wall l2 is an operating nger 23 pivoted on a pin 2t which extends through the slot 25 formed in the bar 22. Fixedly attached to the inner end of the pin is one end of a link 26, the opposite end of which carries a pin2'l which is 25 attached to the bar 22, this bar 22 being provided with the `elongated slot 25 so that it may move vertically, relative to the location of the pin 2Q. By rocking the finger 23 on the pin 2d,

as a pivot, the shutters may be `moved to opened ,30 or closed position.

The forward wall l5 of the housing is provided with the spaced outlet slots 28 and this wall at the upper edge` of each of these slots is placed outwardly to provide the deflecting lip 2Q. 335 Mounted in the housing above the motion of each of the shutters il is an arcuate deiiecting plate 3E which extends from the rear to the forward side of 'the housing. The forward edge of this deiiecting plate t@ is angularly turned as at 3i and brought into engagement and connected to the inner surface of the wall lrby welding or in any other suitable manner. At each of the slots 28, I provide a trough 32 which `extends :from side wall to side wall of the housing and which has the doubling-over flange 33 which snaps over the lower edge 34 of the slots 28. It will be noted that the inner side 35 of the trough, adjacent its upper end, is curved or formed ar-` cuate. 'I'he purpose of this arcuate formation is to cooperate with the arcuate deflecting plate 30 so that the air is deflected into a position to travel over the surface of Water which may be in the trough `32.

To provide Water forthe trough, there is at- M tached to the outer surface of the side wall Il a delivery pipe 36 carrying a tting 34 to which a water pipe may be attached. This delivery pipe communicates with the pipe ,3l through which there is positioned a valve 33 at each of the troughs, This valve communicates with a pipe 3Q leading inwardly to the trough. This construction is such that by adjusting the valve 38, a dripping of water into the troughs may be permitted at a rate according to the return of pressure. By this means, there is consequently maintained a quantity of water in the trough at a predetermined height, and by forcing the air to travel over the surface of this water, foreign particles may be trapped and the air may also be humidied,

In this way, I have provided a register whereby cleanliness may be attained, greater comfort provided by having the air properly humidified, and a neat and attractive register control provided.

While I` have `illustrated and described the preferred form of construction, I do not wish to 'limit myself to the precise details of structure shown, but wish to avail myself of such variations and modifications as may come within the scope of the appended claims. y

What I claim as new is:
